Specification of Letters Patent.

Patented Sept. '7, 1909.

Application filed February a5, 1909. Serial No. 479,905.

To all whom it may concern:

Be it known that we, HERMAN l/VnsLn and HENRY VVEsLn, both citizens ofthe United States, and residents of Medford, in the county of Taylor andState of Wisconsin, have invented a new and Improved Sleigh- Knee, ofwhich the following is a full, clear, and exact description.

This invention relates to sleigh knees, and is an improvement on theconstruction shown in Letters Patent No. 57 2,847 granted to us December8, 1896.

The object of the invention is to provide a strong and more durablemeans for movably attaching the clamp to the sleigh knee proper.

Another object is to improve the means of fastening the sleigh knee tothe runner.

These and other objects will be more fully described hereinafter andmore particularly set forth in the claims.

Reference may be had to the accompanying drawings forming a part of thisspecification, in which like reference characters denote correspondingparts in all the views, and in which Figure 1 is a side elevation,partly in section, to show the improved means of attaching the sleighknee to the runner; Fig.- 2 is a vertical longitudinal section throughthe knee and clamp; Fig. 3 is a bottom plan view of the sleigh knee;Fig. i is a perspective of the fastening lug on the end of the knee; and5 is a side elevation of the clamp removed from the knee.

Referring more particularly to the sepa rate parts of the device, A isthe arched sleigh knee proper. This consists of a body portion 1, havingdepending side flanges 2.

In the flanges 2 on each side of the center of the arch of the knee arelongitudinal slots 3 which slope toward each other along converginglines. Passing through these slots 3 are bolts 4, which pass throughopenings 5 in the depending side flanges of the clamps (3. The clampsare thus strongly fastened to the sleigh knee with freedom for pivotalsliding motion, which is limited by lugs 7 on the body portion 1. Theclamp 6 further consists of a main portion 8, having fastening openings9 and countersunk openings 10, which, together with upwardly-extendingflan cs 11, are adapted to fasten said clamps to the body of a sleigh.Through openings 11 in the side flanges 2, bolts or any other suitablemeans fasten the sleigh knee to the runner 12. Additional means forsecuring the sleigh knee to the runner is afforded by perforated conicallugs 13, which are inset in the runner and held thereto by screw-bolts14:. This lug and screw means of fastening prevents any possible endmotion, and also prevents the ends from being cantedup by any excessiveload.

By sloping the slots 3 toward each other, they form a guide for thebolts 4, which is substantially concentric with the curved up per andlower surfaces of the arched body portion 1 and the clamp 6respectively, so that the clamp 6 is permitted to have an arcuaterocking motion relative to the body portion.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent is" 1. In a device of the class described, thecombination with a clamp having a curved lower surface, of a bodyportion having a curved upper surface coinciding with the curved lowersurface on said clamp, and also having a plurality of converging slotsforming a guide substantially concentric with said curved surfaces, andmeans engaging said slots adapted to rockingly secure said clamp to saidbody portion.

2. In a device of the class described, the combination with a clamphaving a concave curved lower surface, of a body portion having a convexcurved upper surface coincid ing with the lower surface on said clamp, arunner for said body portion, downwardlyextending flanges, havingconverging slots substantially concentric with said curved portions onsaid clamp and said body portion and adapted to overlap the sides ofsaid runner, means for engaging said slot in said body portion, forsecuring said clamp to said body portion, perforated conical lugs onsaid body portion adapted to engage said runner, and means inserted insaid lug adapted to secure said body portion to said runner.

In testimony whereof we have signed our names to this specification inthe presence of 7 two subscribing witnesses.
